GEORGE C. LUCAS, OF CLEVELAND, OHIO.

RAILWAY-FROG.

To all whom it may concern:

Be it known that I, GEORGE O. LUCAS, a citizen of the United States, and a resident of the city of Cleveland, State of Ohio, have invented certain new and useful Improvements in Railway-Frogs, of which the following is a specification, accompanied by drawings.

My invention relates to a railway frog of that class in which the center portion or frog body, in order to withstand hard service, is made of some especially hard and tough material, such as manganese steel. This material, as is well known, cannot readily be shaped by ordinary tools, but must be ground by emery wheels.

One object of my invention is to produce a frog that shall be very durable in service and yet require little work of fitting, and this I attain by so shaping the center portion or body of the frog that it can be cast (or forged) into practically its finished forni, and by so shaping those parts against which the rails iit that the rail ends will lit thereto with but little shaping. The invention further relates to the Imanner of combining the various parts of the frog, so that they will by mutual connection and interlocking form a self-con tained practically unitary structure.

In the accompanying drawings, Figure 1 is a plan view of one form of frog; Fig. 2 is a plan view of the frog body 3 Fig. 3 is a sectional view on the line 3 3 looking towards the left. Fig. 4 is a sectional view on the line 4 4; Figs. 5, 6, 7, and 8 are sections of Fig. 1 on the lines 5, 6, 7, S, respectively. Fig. 9 is a plan view of a modification. Fig. 10 is a cross section thereof on the plane 1.0-10. Fig. 11 shows in plan View the invention as applied to a double frog. Figs. 12 and 13 are cross sections on the lines 12 andv 13 of Fig. l1.

The cross sections are on a larger scale than the plan views.

In the form illustrated in Figs. 1 to 8 a single point frog is shown in which the hard center or frog body is preferably a casting or forging of manganese steel or other suitable material of the form shown in Figs. 2, 3, and 4. Against this frog body the track rails and the two wing rails abut. The frog body fits the rails in such a manner that very little fitting of the rails is required.

The frog body B has a point against which the two track rails C abut, and lateral raised portions or heads 21 against which abut at one end the two track rails D and at Specification of Letters Patent.

the other end the wing rails E. Between the lateral heads 21 and the point 20 the grooves 23 to admit the flanges of the wheels are formed. The side faces of the 1cody B are channeled and contoured like the side of a rail, so that the abutting rails D and E which meet the heads 21 and are in alinement therewith, can be directly spliced thereto by means of the angle splice bars 30. It will be seen that the lateral raised portions or heads 21 entirely interrupt and take the place of the rails D and E which abut and are alined with these portions. The frog body B forms, in fact, a complete frog entirely interrupting the rails and replacing them with a hard durable frog body. Between the rails D the frog body is provided with a toe extension 24 which is fitted to the channels of the rails D, as shown in Fig. 8. Preferably a separate filler block F may also be used.

At 25 inclines are shown for receiving the false flanges of the treads of worn wheels where the head portions 21 widen out from the rail D. At the other end the frog body has a heel extension 26 which fits -the channels of the rails C where they abut against the point 20. Ailler block G may be added between the rails C where the angle is small, and filler blocks H may be fitted between the rails E and C. In using the expression "rails it will be understood that I mean also to include short pieces of rail such as the wing rail E. As shown in the section (Fig. 6) the frog body is fitted to the channels of the two wing rails E at 28 near their ends.

It will be seen that where each of the track rails and wing rails meet the frog body, their ends abut against a raised portion which forms a continuation of the rail, while the rail ends on one side receive portions of the frog body that fit into the channels of the rails similarly to filler blocks. Consequently the rails only require to be cut ofi squarely or at an angle, as the case may be, and secured to the frog body. The sides of the raised heads 21 and of the frog body are contoured like the rails, as best seen in Figs. 4 and 7, having channels with overhanging heads and bottom ianges like the rails. Consequently the splice bar 30, which is preferably an angle splice, as shown, can fit and be secured to the side of the frog body and to the rails D and E. Bolts are provided at frequent intervals, as shown, and serve to imite all the parts into a structure which, by reason of the shape of the frog body, holds the rails very securely to the frog body, giving very strong support against vertical as well as horizontal displacement of any of the parts.

Fig. 9 shows a single point frog of somewhat broader' angle than Fig. 1. The point 20 has a heel extension 40 which comes up to the track level between the heads of the rails C and is tapered or inclined to receive the treads of the worn wheels, as will be well understood. At the other end, instead of one toe extension 24, two outside toe extensions 42 from the lateral raised heads 21 are shown which fit against and receive the outer sides of the converging rails D, and a bent or U- shaped splice bar J between the converging rail ends is bolted through the rails to the toe extensions 42. The toe extensions 42 should be tapered as at 43.

Fig. 11 shows the invention as applied to a two-point frog or center frog. In such frogs I may omit the lateral head portion 21 on one side over which the treads of the wheels do not pass, and employ a bent guard rail K. The two points 20 may be similar to either Fig. 1 or Fig. 2, and the angle being sufficient, I have shown them provided with projections 40, as in Fig. 2. In this structure the running rails are shown at L and M; the rails P are caser rails bolted to the rails M. The rails Q are guard rails which abut against the points 20 and fit the extensions 40. It are short rails slightly tapered to lead up to the raised lateral portion 21. The angle splice bar 31 is boltedto the contoured side of the raised or head portion 21 of the frog body and to the rails R and through the rails L, Q, M and K, some of the bolts extending through all these members. It will be seen that this construction shown in Figs. 11, 12 and 13, in common with the other forms shown, provides a frog body which entirely interru ts the track rails and takes their place, an is provided with a lateral raised portion or head 21, the side of which is contoured like a rail 1a)nd secured to abutting rail ends by a splice I claim the following:
